Blogger Charlie Stross does a remarkable job of tying everything together in this post–which says that Jobs’ aversion to Flash is really about Apple, and the rest of the computer industry, facing a life-or-death struggle over the next few years as PCs get even more commoditized and even more of our digital lives move online. Apple, Stross says, is trying to reinvent itself from a manufacturer of Macs into a gatekeeper and provider of services, and it’s trying to do it while it still has time.

One striking, subtle point about Jobs’s memo: He says “Flash was created during the PC era…” In other words, he’s saying we’re no longer in the PC era. Stross says that “the PC revolution is almost coming to an end,” which seems like as good a way to describe where we are as any.

You can quibble with bits and pieces of Stross’s overarching analysis–or the whole damn thing if you want–but it’s incredibly thought provoking. Having grown up in Boston in the 1980s, where Route 128 was lined with wildly successful minicomputer companies which no longer exist, I’m certainly not discounting the possibility that PCs will cease to exist sooner than we expect, and that none of the huge companies that make them is guaranteed an afterlife.
